Autonomous control system for agile imaging satellite

Abstract

The invention discloses an autonomous control system for an agile imaging satellite. The imaging satellite is provided with a satellite-borne replanning sub-system and a real-time task receiver; the real-time task receiver is used for carrying out real-time short message information interaction between the imaging satellite and users and between the imaging satellite and a ground supporting system; the replanning sub-system comprises a task preprocessing module, a test replanning module and a command generating module; the task preprocessing module is used for decomposing a target into a plurality of meta tasks and converting the target indication information of each meta task into target guide information; the task replanning module is used for receiving a preprocessing result and generating a new task planning scheme; and the command generating module is used for generating a satellite command from the generated task planning scheme and transmitting the satellite command to a satellite task sub-system for execution. According to the autonomous control system disclosed by the invention, the task planning scheme can be autonomously and partially adjusted according to the decided satellite task planning scheme and task requirements received in real time, so that in-time response to real-time tasks is realized, and the actual observation efficiency is improved.

Description

technical field [0001] The invention relates to an autonomous operation and control system of an agile imaging satellite. Background technique [0002] If an imaging satellite wants to efficiently realize the earth observation task, it needs the joint completion of the operation and control center, the measurement and control center, the ground station and the satellite in orbit. It is usually customary to collectively refer to the operation and control center, measurement and control center, and ground station as the ground support system. An imaging satellite itself constitutes an on-board system, which generally includes a star service subsystem, an antenna subsystem, an attitude control subsystem, and an imaging payload subsystem. system, data storage subsystem, power supply subsystem and temperature control subsystem, etc. [0003] The current observation task planning is usually carried out on the ground, and the planning period varies from one day to several days.

Problems solved by technology

With the enhancement of these capabilities, there are higher requirements for satellite application goals. Obviously, the traditional satellite ground control mode can hardly meet the satellite observation tasks with high timeliness and reliability requirements.
